如何在json解析为OpenStruct时解决额外的"表"和"可修改"合并问题

Question

JSON.parse(response, object_class: OpenStruct) rescue response

我的rails应用程序有上面一行代码，这导致了一个奇怪的问题。这里response来自外部API调用，看起来像下面的

"{"payable_amount":80.0,"qr_data":{"data":"upi://pay?pa=paytm-@paytm&&mc=&tr=&am=80&cu=INR&paytmqr=","image":"+1OqeGDVfgX5Thh2X4Yf2P8B8/it24m51v9gAAAABJRU5ErkJggg=="},"transaction_id":387400583,"success":true}"

当我将应用程序作为一个整体运行时，JSON.parse()之后的结果如下所示:

"{"table":{"payable_amount":80.0,"qr_data":{"table":{"data":"upi://pay?pa=paytm-@paytm\u0026\u0026mc=5411\u0026tr=\u0026am=80\u0026cu=INR\u0026paytmqr=","image":"+1OqeGDVfgX5Thh2X4Yf2P8B8/it24m51v9gAAAABJRU5ErkJggg=="},"modifiable":true},"transaction_id":387400583,"success":true},"modifiable":true}"

table&modifiable字段是意外的，'&'也搞砸了，奇怪的是，当我从rails控制台逐行执行代码时，它不会发生。

我已经通过做JSON.parse(response).deep_symbolize_keys!修复了这个问题，但仍然对这个问题感到困惑。

如果您包含导致混乱结果的实现，将更容易提供帮助。

无论如何，看起来to_json正在某处的OpenStruct对象上被调用:

> response = "{"payable_amount":80.0,"qr_data":{"data":"upi://pay?pa=paytm-@paytm&&mc=&tr=&am=80&cu=INR&paytmqr=","image":"+1OqeGDVfgX5Thh2X4Yf2P8B8/it24m51v9gAAAABJRU5ErkJggg=="},"transaction_id":387400583,"success":true}"
> parsed_response = JSON.parse(response, object_class: OpenStruct)
> parsed_response.to_json
=> "{"table":{"payable_amount":80.0,"qr_data":{"table":{"data":"upi://pay?pa=paytm-@paytm\u0026\u0026mc=\u0026tr=\u0026am=80\u0026cu=INR\u0026paytmqr=","image":"+1OqeGDVfgX5Thh2X4Yf2P8B8/it24m51v9gAAAABJRU5ErkJggg=="}},"transaction_id":387400583,"success":true}}"
